Hi,
I inserted an GLAnimCanvas in an JPanel which size is 931652. In the GLAnimCanvas I draw a simple quad which size is 0.056.01 but it seems the quad is to big because it goes out of the JPanel I just see the top. I don’t know how to configure these problems of size…
I defined the gl.glViewport method with the size of the JPanel… as I saw in all examples
Could somebody help me?
Thank you in advance
Mat
Hi Mat,
This could be several things:
i) If your viewport is set up incorrectly gl will only render to part of your window. Make sure you call glViewport(0, 0, window_width, window_height).
ii) Your projection (gluPerspective/glFrustum/glOrtho) may be set up wrong. I think that the default is an orthographic projection (left: -1, right: 1, top: 1, bottom: -1).
iii) You may be translating (glTranslate) the object such that only half of it is visible.
I can’t tell exactly what it is from your description, but check each of these and you should find the problem.
